2012-02-24MEM: Make port proxies use references rather than pointersAndreas Hansson
This patch is adding a clearer design intent to all objects that would not be complete without a port proxy by making the proxies members rathen than dynamically allocated. In essence, if NULL would not be a valid value for the proxy, then we avoid using a pointer to make this clear. The same approach is used for the methods using these proxies, such as loadSections, that now use references rather than pointers to better reflect the fact that NULL would not be an acceptable value (in fact the code would break and that is how this patch started out). Overall the concept of "using a reference to express unconditional composition where a NULL pointer is never valid" could be done on a much broader scale throughout the code base, but for now it is only done in the locations affected by the proxies.
2012-01-17MEM: Add port proxies instead of non-structural portsAndreas Hansson
Port proxies are used to replace non-structural ports, and thus enable all ports in the system to correspond to a structural entity. This has the advantage of accessing memory through the normal memory subsystem and thus allowing any constellation of distributed memories, address maps, etc. Most accesses are done through the "system port" that is used for loading binaries, debugging etc. For the entities that belong to the CPU, e.g. threads and thread contexts, they wrap the CPU data port in a port proxy. The following replacements are made: FunctionalPort > PortProxy TranslatingPort > SETranslatingPortProxy VirtualPort > FSTranslatingPortProxy --HG-- rename : src/mem/vport.cc => src/mem/fs_translating_port_proxy.cc rename : src/mem/vport.hh => src/mem/fs_translating_port_proxy.hh rename : src/mem/translating_port.cc => src/mem/se_translating_port_proxy.cc rename : src/mem/translating_port.hh => src/mem/se_translating_port_proxy.hh
2011-04-15trace: reimplement the DTRACE function so it doesn't use a vectorNathan Binkert
At the same time, rename the trace flags to debug flags since they have broader usage than simply tracing. This means that --trace-flags is now --debug-flags and --trace-help is now --debug-help

2006-06-06Change ExecContext to ThreadContext. This is being renamed to differentiate ↵Kevin Lim
between the interface used objects outside of the CPU, and the interface used by the ISA. ThreadContext is used by objects outside of the CPU and is specifically defined in thread_context.hh. ExecContext is more implicit, and is defined by files such as base_dyn_inst.hh or cpu/simple/base.hh. Further renames/reorganization will be coming shortly; what is currently CPUExecContext (the old ExecContext from m5) will be renamed to SimpleThread or something similar. src/arch/alpha/arguments.cc: src/arch/alpha/arguments.hh: src/arch/alpha/ev5.cc: src/arch/alpha/faults.cc: src/arch/alpha/faults.hh: src/arch/alpha/freebsd/system.cc: src/arch/alpha/freebsd/system.hh: src/arch/alpha/isa/branch.isa: src/arch/alpha/isa/decoder.isa: src/arch/alpha/isa/main.isa: src/arch/alpha/linux/process.cc: src/arch/alpha/linux/system.cc: src/arch/alpha/linux/system.hh: src/arch/alpha/linux/threadinfo.hh: src/arch/alpha/process.cc: src/arch/alpha/regfile.hh: src/arch/alpha/stacktrace.cc: src/arch/alpha/stacktrace.hh: src/arch/alpha/tlb.cc: src/arch/alpha/tlb.hh: src/arch/alpha/tru64/process.cc: src/arch/alpha/tru64/system.cc: src/arch/alpha/tru64/system.hh: src/arch/alpha/utility.hh: src/arch/alpha/vtophys.cc: src/arch/alpha/vtophys.hh: src/arch/mips/faults.cc: src/arch/mips/faults.hh: src/arch/mips/isa_traits.cc: src/arch/mips/isa_traits.hh: src/arch/mips/linux/process.cc: src/arch/mips/process.cc: src/arch/mips/regfile/float_regfile.hh: src/arch/mips/regfile/int_regfile.hh: src/arch/mips/regfile/misc_regfile.hh: src/arch/mips/regfile/regfile.hh: src/arch/mips/stacktrace.hh: src/arch/sparc/faults.cc: src/arch/sparc/faults.hh: src/arch/sparc/isa_traits.hh: src/arch/sparc/linux/process.cc: src/arch/sparc/linux/process.hh: src/arch/sparc/process.cc: src/arch/sparc/regfile.hh: src/arch/sparc/solaris/process.cc: src/arch/sparc/stacktrace.hh: src/arch/sparc/ua2005.cc: src/arch/sparc/utility.hh: src/arch/sparc/vtophys.cc: src/arch/sparc/vtophys.hh: src/base/remote_gdb.cc: src/base/remote_gdb.hh: src/cpu/base.cc: src/cpu/base.hh: src/cpu/base_dyn_inst.hh: src/cpu/checker/cpu.cc: src/cpu/checker/cpu.hh: src/cpu/checker/exec_context.hh: src/cpu/cpu_exec_context.cc: src/cpu/cpu_exec_context.hh: src/cpu/cpuevent.cc: src/cpu/cpuevent.hh: src/cpu/exetrace.hh: src/cpu/intr_control.cc: src/cpu/memtest/memtest.hh: src/cpu/o3/alpha_cpu.hh: src/cpu/o3/alpha_cpu_impl.hh: src/cpu/o3/alpha_dyn_inst_impl.hh: src/cpu/o3/commit.hh: src/cpu/o3/commit_impl.hh: src/cpu/o3/cpu.cc: src/cpu/o3/cpu.hh: src/cpu/o3/fetch_impl.hh: src/cpu/o3/regfile.hh: src/cpu/o3/thread_state.hh: src/cpu/ozone/back_end.hh: src/cpu/ozone/cpu.hh: src/cpu/ozone/cpu_impl.hh: src/cpu/ozone/front_end.hh: src/cpu/ozone/front_end_impl.hh: src/cpu/ozone/inorder_back_end.hh: src/cpu/ozone/lw_back_end.hh: src/cpu/ozone/lw_back_end_impl.hh: src/cpu/ozone/lw_lsq.hh: src/cpu/ozone/lw_lsq_impl.hh: src/cpu/ozone/thread_state.hh: src/cpu/pc_event.cc: src/cpu/pc_event.hh: src/cpu/profile.cc: src/cpu/profile.hh: src/cpu/quiesce_event.cc: src/cpu/quiesce_event.hh: src/cpu/simple/atomic.cc: src/cpu/simple/base.cc: src/cpu/simple/base.hh: src/cpu/simple/timing.cc: src/cpu/static_inst.cc: src/cpu/static_inst.hh: src/cpu/thread_state.hh: src/dev/alpha_console.cc: src/dev/ns_gige.cc: src/dev/sinic.cc: src/dev/tsunami_cchip.cc: src/kern/kernel_stats.cc: src/kern/kernel_stats.hh: src/kern/linux/events.cc: src/kern/linux/events.hh: src/kern/system_events.cc: src/kern/system_events.hh: src/kern/tru64/dump_mbuf.cc: src/kern/tru64/tru64.hh: src/kern/tru64/tru64_events.cc: src/kern/tru64/tru64_events.hh: src/mem/vport.cc: src/mem/vport.hh: src/sim/faults.cc: src/sim/faults.hh: src/sim/process.cc: src/sim/process.hh: src/sim/pseudo_inst.cc: src/sim/pseudo_inst.hh: src/sim/syscall_emul.cc: src/sim/syscall_emul.hh: src/sim/system.cc: src/cpu/thread_context.hh: src/sim/system.hh: src/sim/vptr.hh: Change ExecContext to ThreadContext. --HG-- rename : src/cpu/exec_context.hh => src/cpu/thread_context.hh extra : convert_revision : 108bb97d15a114a565a2a6a23faa554f4e2fd77e

(Multiple systems not yet yested though.) Also changes to build sim_smt in full-system mode (though with only SimpleCPU and not the full timing CPU for now). Still to do: minimize changes in SimpleCPU code between full-system and application modes... way too many ifdefs there. Much of the full-system stuff moved into SimpleCPU should be put in a new System object to allow multiprocessor simulations. Converted last remaining modules from C to C++ (mostly in /old). Renamed all .c files to .cc and a few .h files to .hh. Renamed architecture-specific files in arch/$TARGET from $TARGET.{cc,hh,def} to machine.{cc,hh,def} to get rid of pointless intermediate files in object directory. Split exo-specific definitions out of machine.hh into machine_exo.h. Specifics: In machine.def, null resource descriptors must be FUClamd_NA (and not NA) to pass C++ type checking. Enhanced error checking/reporting in bas src/arch/sparc/vtophys.cc: - Get rid of my String class, the Vector class, the bitvector class, and my doubly linked list class. - Convert tokenize, to_number (formerly StringToNumber) and eat_white to function on stl strings. - Change most cases of char * and const char * to string, or const string & - Some formatting and style nits, but not too many. src/arch/sparc/vtophys.cc: simplify src/arch/sparc/vtophys.cc: Renamed SimpleCPU::(read|write)_(byte|half|word|qword) to just read & write, overloaded on the type of the 'data' argument. Merged the full-system and non-full-system implementations of these eight original functions into two common template functions. To support this, also renamed (read|write)[1248] on memory_object and derivatives to just read & write, again overloaded on the type of the 'data' argument. Many of these functions could now be condensed into a few template functions (though with a level of indirection so that the interface can remain virtual). I did not do that though. src/arch/sparc/vtophys.cc: First pass at compiling with gcc 3.x. Lots of "std::" in header files, "using namespace std" in source files. (Note policy of not putting "using" statements in headers or before includes in sources.) Still not able to compile with gcc 3.2. Errors: - Can't create an ifstream from a file descriptor anymore (breaks IniFile). - "`class MSHR::MSHRegister' is private" errors in mshr.cc and prefetch_cache.cc: not clear why since it's in the public part of the class declaration. - cpu.cc:879: can't match a reference and 0 (specifically "no match for `bool ? SimObjectParam<PipeTrace*>& : int' operator") - pipetrace.cc: "invalid conversion from `int' to `std::_Ios_Fmtflags'" Warnings: - strstream now deprecated... needs some rewriting in sat_counter.hh and hybrid_pred.hh (need to get all that code out of the headers anyway) - trace.hh macro problem: cpp now says 'pasting "::" and "Event" does not give a valid preprocessing token' - major "implicit typename" issues in base/sized.hh src/arch/sparc/vtophys.cc: src/arch/sparc/vtophys.hh: Implement some interval statistics for full system mode. Create a callpal function that is called when a callpal occurs so it's easier to manipulate the statics. Rework the vtophys stuff to make it a bit cleaner. src/arch/sparc/vtophys.cc: src/arch/sparc/vtophys.hh: Get rid of almost all old-style object names.
